Four years and hundreds of millions of dollars in investment capital later, Trion World Network finally has a couple of "connected" games to show ... and a new name, to boot. Now known as Trion Worlds, the company held an event in San Francisco last week to take the wraps off of the Petroglyph-developed "MMORTS" End of Nations and its home-grown MMORPG Rift: Planes of Telara (formerly known as Heroes of Telara).

End of Nations is the latest game from the developer of Mytheon, Star Wars: Empire at War and Universe at War, which hopes to break new ground in the RTS genre by introducing elements such as a persistent game world and player-vs-environment battles that support more than 50 players simultaneously. It's set in a near future where resistance fighters battle a totalitarian one world government that possesses superior technology, including battleship-sized tanks called Panzer Hulks.

Shown at E3 last year, Rift: Planes of Telara has undergone more than a name change. The game's visuals have improved substantially and its new hook -- "rifts" that appear randomly and spawn creatures from other dimensions -- is something Trion Worlds is focusing heavily on, calling it "dynamic content" that only its server platform can deliver. (Peep the Rift: Planes of Telaraimage gallery here.)

Both games are due out in 2011 and are expected to be playable at E3 in June. The company is also working with Syfy on a hybrid action MMO / TV series believed to be calledOne Earth. The project is not being shown just yet, but it was revealed that factions and players from the game will be written into the show -- should they emerge victorious in tie-in challenges. We were also told by a Trion World rep that the game, while currently announced only for PC, will likely be released for console platforms.
